If you don't own an all American pressure canner you should. All others pale in comparison.
I have been canning stuff since 1989. I have been smoking and canning stuff since 1989. Lots of experiments and lots of failures.
I get fish coming out the best. Chicken 2nd. 27 quart canner.
Deer isn't canned here because of the tannins. I don't eat second day deer left overs. Maybe in a tomato based stock. Still wouldn't waste my deer potential sausage for canning.
